Abstract

A method of determining a type of a disc for a disc system to record/reproduce a plurality of recordable discs having different track pitches, including detecting a plurality of signals for determination while moving an objective lens up or down and simultaneously making the objective lens vibrate in a radial direction of the disc, and determining the types of the discs having different track pitches by using the detected signals for determination.
